Introduction
The Helios PD2-6060 is a multi-purpose, easy to use, large-display dual-input process meter
ideal for level, flow rate, temperature, or pressure transmitter applications. It features large 1.8
inch superluminous LED digits, which can be read from up to 100 feet away. It is housed in a
water-resistant, field mountable NEMA 4X/IP65 rated enclosure for convenient indoor or outdoor
installation.
The meter accepts current and voltage signals (e.g. 4-20 mA, 0-10 V). Various math functions
may be applied to the inputs including addition, difference, absolute difference, average,
weighted average, multiplication, division, minimum, maximum, draw, ratio, and concentration.
This is in addition to the signal input conditioning functions (linear, square root, programmable
exponent, or round horizontal tank calculations).
The displays, relays, and the analog output may be assigned to input channels A or B, or math
result channel C. Three of the programming buttons can be set for custom operation. The
analog input can be scaled to display the process in two different scales; for example, the main
display could indicate level in feet and the second display could indicate the volume in gallons.
A fully loaded Helios PD2-6060 meter comes with four (4) SPDT relays, a 4 20 mA output, two
24 VDC power supplies, five (5) digital inputs and four (4) digital outputs, and RS485 serial
communications. The four relays can be used for alarm indication or process control
applications such as pump alternation control. The 4-20 mA isolated output, Modbus RTU serial
communications, and digital I/O features make the Helios an excellent addition to any system.
